Information processing device and method using display for auxiliary light

Abstract

In an information processing device configured to include an imaging unit, a display unit, and an illumination sensor, to capture image information by the imaging unit, and to perform processing on the captured image information, the display unit and the imaging unit are disposed on the same surface, the capture processing is performed in a normal mode when a detected value of the illumination sensor is a predetermined value or more, and the capture processing is performed in a dark-place mode when the detected value of the illumination sensor is a predetermined value or less.

The invention claimed is: 
     
       1. An information processing device comprising:
 an imaging unit; 
 a display unit; and 
 an illumination sensor, 
 wherein the imaging unit and the display unit are disposed on a first surface side of the information processing device, 
 wherein there is provided a mode of using at least an area of the display unit to display auxiliary light, in a case of taking an image by the imaging unit when a detected value of the illumination sensor is a predetermined value or less, 
 wherein a size of the area of the display unit that displays the auxiliary light is adjusted in response to a subject recognition result obtained from video information taken by the imaging unit before taking the image by the imaging unit, and 
 wherein at the time of taking the image by the imaging unit the entire display of the display unit displays the auxiliary light. 
 
     
     
       2. The information processing device according to  claim 1 ,
 wherein in a case of taking an image by the imaging unit when the detected value of the illumination sensor is the predetermined value or less, image information captured by the imaging unit is displayed in a first region of the display unit, and 
 image information different from the image information is displayed in a second region of the display unit at a luminance higher than a luminance in the first region. 
 
     
     
       3. The information processing device according to  claim 2 ,
 wherein, the luminance in a first part of the second region closer to the first region is lower than the luminance in a second part of the second region farther from the first region. 
 
     
     
       4. The information processing device according to  claim 2 ,
 wherein the luminance in the second region of the display unit is approximately uniform. 
 
     
     
       5. The information processing device according to  claim 2 ,
 wherein luminance in the second region of the display unit changes depending on a detected value in the illumination sensor. 
 
     
     
       6. The information processing device according to  claim 2 ,
 wherein the second region of the display unit is disposed on any one of left, right, top, and bottom sides of the first region. 
 
     
     
       7. The information processing device according to  claim 1 ,
 wherein the display unit through-displays image information obtained by performing light-quantity increase processing on image information captured by the imaging unit, and is switched to display the auxiliary light at a luminance higher than a luminance of the image information when receiving an instruction from a user so as to record image information captured by the imaging unit in a state of the through-display. 
 
     
     
       8. An information processing method using an information processing device including an imaging unit, a display unit, and an illumination sensor, the imaging unit and the display unit being disposed on a first surface side of the information processing device, the method comprising the steps of:
 detecting illumination by the illumination sensor; 
 setting a mode of using at least an area of the display unit to display auxiliary light, in a case of taking an image by the imaging unit when a detected value of the illumination sensor is a predetermined value or less; and 
 adjusting a size of the area of the display unit that displays the auxiliary light in response to a subject recognition result obtained from video information taken by the imaging unit before taking an image by the imaging unit; and 
 displaying the auxiliary light on the entire display of the display unit at the time of taking the image by the imaging unit. 
 
     
     
       9. The information processing method according to  claim 8 , further comprising the step of:
 displaying image information captured by the imaging unit in a first region of the display unit, and displaying image information different from the image information in a second region of the display unit, at a luminance higher than a luminance in the first region, when the mode is set. 
 
     
     
       10. The information processing method according to  claim 8 , further comprising the step that:
 when the mode is set, the display unit through-displays image information obtained by performing light-quantity increase processing on image information captured by the imaging unit, and is switched to display the auxiliary light at a luminance higher than a luminance of the image information when receiving an instruction from a user so as to record image information captured by the imaging unit in a state of the through-display.
